Precautions
Use of chemicals: Avoid contact with ammonia, amines, alkali solutions, aromatic hydrocarbons, ketones, esters, and halogenated hydrocarbons as polycarbonate resins are used.
Use of flux: Avoid using water-soluble flux during soldering to prevent adverse effects on materials.
Soldering: Avoid designs where molten solder flows over the PC board surface to prevent imperfect contacts.
Recommended circuit configuration: Recommended for voltage adjustment. Confirm performance when used for current adjustment.
Residual Resistance: Standard units have silver electrodes with anti-sulfurization coating. Contact for low residual resistance requirements.
Dew condensation: Avoid use in conditions where dew or water drops may occur to prevent insulation failure or shorting.
Operation at Low Temperature: Customized products for smoother operation in low-temperature environments are available upon request.
